I've paid as little as $25 and as much as $125. I really haven't bought one that I didn't think I was getting a really good deal on based more on condition than color.
If you have not used one and are used to working with straight out kettles you'll love it. Looks like there is one for the taking right close to you for $125. Seems to be in great shape, price is right, or make an offer
If I was in the market I would take a look and if it was in great shape I'd buy it $125 especially if it includes a cover. You might find something similar for less but I sure have seen them for more...
